To all 107mm t may concern.'

Be it known that I, GILBERT W. ALLEN,Y a citizen of the United States, residing-at..

Cherry Creek, in the county of Chautauqua and StateA of New York, have invented certain new 'and useful Improvements in Thermostatically-Operated Burners for Lamps for I-Ieating Incubators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in heating apparatus for incubators and especially in the provision of` a thermostatically-operated device whereby the intensity of the iiame from the wick of an oil burner may be regulated without dis- Y torting the flame.

The invention consists more specifically in the provision of an elongated iattened tube having a vertical movement over the wick tube and serving to retain a perfect blaze at all times, equal to the effect produced by the raising and lowering of the wick by the usual turning screw.

The present invention comprises other detailed features, combinations and arrangements of parts which will be hereinafter fullyA described, shown in the accompanying drawings and then specifically defined in the appended claim.

My invention is illustrated in the accompanying drawings, in which Figure l is a view showing a thermostatically-operated lever connected to the means for regulating the intensity of the flame of the burner.

Fig. 2 is an enlarged detail sectional view through the burner and movable flame regulating member mounted about the wick tube.

Fig. 3 is a side elevation.

Reference now beinghad to the details of the drawings by letter, A designates a thermostatically-operated element of the usual construction adapted, when acted upon by different degrees of temperature, to cause a tilting of the lever B to which it is attached.

Said lever is adapted to be pivotally mounted upon the frame of an incubator. In the present instance, I have shown the application of my invention to an ordinary oil lamp, designated by letter C, and provided witha wick D mounted in a wick tube Ill upon the burner F, the latter fitting the lamp with threaded connections as usual. In order to permit the font of the lamp to be filled without unscrewing the burner, a filling tube II is secured to the burner in the manner shown.

Mounted to have a vertical play about the wick tube is a flat tubular member K conforming to and of slightly larger area than the wick tube and which-flat tubular member is secured at its lower end to a disk N of suflicient weight to cause the flat tubulail member to normally rest at its lowest limit of movement, in which position the upper edge of the wick tube and said flat tubular member will be flush, thus allowing the fiame from the wick within the tube to burn freely.

A lever, designated by letter R, is pivotally mounted upon the loop P upon the under side of the burner and has one arm positioned underneath said disk and its other end engages the lever B.

In operation, when the lever B is tilted incident to the expansion of the thermostatic element, a similar movement will be imparted to the lever pivoted upon the burner and causing the fiat telescoping tube to be raised a slight distance for the purpose of reducing` the intensity of the flame from the wick of the burner, the movement of said flat tube having the same effect as the lowering of the wick to reduce the size of the flame,

IIeretofore, it has been attempted to regulate the intensity of the flame of a burner by thermostafically-operated mechanism by the employment of means which impinges upon the sides of the flame to constrict the same or otherwise changing the blaze but which has been found objectionable.

By the provision of a flat tubular telescopnicety by the delicate thermostatically-open l" i:

ated movements imparted to the levers whereby the telescoping member may be raised and lowered.

What I claim to be new is A thermostatically-operated device for l heating incubators, etc., comprising a burner having a shell with a wick tube, said shell of the burner having :L 'fiat portion aboutsaid beyond the circumference oi` `the burner, al tube which is provided with a, slot, e lever thermostzttically-operated tiltingV member pivoted at one side of its center to said shell one end of which is adapted to engage the underneath the' same and having a bowed outer erin of said lever, as set forth.
